For this assignment, you need to come up with ONE one proportion claim and analyze your claims in Minitab using the Project 2 Class Data and then do any needed follow-up. The following video provides a walkthrough of this assignment and some helpful hints!
For this assignment work through the information below step-by-step to do a one proportion hypothesis test in Minitab. You can just provide the answers for each step (on your paper you submit) OR you can write this up in full sentence/paragraph format, which is what you'll need to do for the Project 2 paper (recommended).
Step 1: Write your Claim
The Step 1 directions will help you write your claim correctly, but you only need to provide your response to #5 (your claim) for Step 1 on your assignment. If you'd like to include the information from 1-5 you can, but it is not needed. Just the wording of your claim is needed.
- Pick one of the following questions that you'd like to analyze using Minitab:
- Question 1: Did you grow up in a household with guns? [Yes, No]
- Question 2: Do you support allowing concealed carry in more places? [Yes, No]
- Pick one of the answer options from the question you picked in #1.
- Example: If you picked Q1, you would then pick either the answer option Yes or No.
- What is the percent from the Pew article for the answer option you picked for #2? For example, if you picked Q1 and yes, the percent would be 48%.
- Q1: Grow Up - Yes = 48%; No = 52%
- Q2: Conceal Carry - Yes = 45%; No = 55%
- Do you think the percentage from Pew (from #3) is higher, lower, or equal to the data we collected?
- Example: I think our responses to Q1 and Yes, is higher than the results from Pew.
- This is your best-educated GUESS, do not look at the data and then make your guess.
- Take the information from #1-4 to write your claim.
- Example: For Q1 and the yes answer option Pew found 48%. Claim - The percentage of people in our survey who grew up in a household with guns is higher than 48%.
- Claims must be based on the percentage found from the Pew study. Do not use the percentages we found in our study!
- Claims have to be written in an appropriate manner for a one proportion test, so review the course resources to see how to write your claim correctly.
Step 2: Information about your Claim & the Statistical Test you are Using
Provide your answer to #1-#2 below on your assignment.
- Is your claim the null or alternative claim?
- State specifically why a one-proportion test is appropriate to use for this claim. So why would you analyze your data with a one proportion test instead of a different statistical test? [Hint, go back to what a one proportion test is used to determine from the class notes.]
Step 3: Analyze the Data using Minitab
Using the Project 2 Data, provide your answer to #1-#2 on your assignment.
- Use Minitab to analyze your claim and copy (as a PNG image) ALL of the Minitab output into your assignment except the graph (95% Upper bound for the Proportion).
- Provide the appropriate statistics/information from the Minitab output that allows you to make a decision about your claim. This information must be typed out on your assignment.
- Sample p
Step 4: Provide a Conclusion & Explanation of your Results
Provide your answer to 1-2 on your assignment.
- Provide a conclusion that answers the original question/claim. Use this exact format:
- There [IS, IS NOT] enough evidence to [Support, Reject] the claim that.... [Restate your claim from Step 1 above].
- Provide a real-world explanation for these results. What do the results of your Minitab analysis actually mean? Things to think about when you try to answer this question: Is our class data different than the results of the PEW survey/article? If so, then explain HOW our results differ from Pew. If our results don't differ statistically, then talk about what the data does show.
Step 5: Is any follow-up testing needed?
- Review your results from Step 4 and determine if any follow-up testing is needed. Explain why or why not.
- If follow-up is needed, then go ahead and do the follow-up and include the results. Information to include if follow-up is needed:
- Follow-up claim you are testing.
- Minitab output
- Minitab results - There [IS, IS NOT] enough evidence to [REJECT, SUPPORT] the claim that... restate follow-up claim.
Real-world explanation of results.
Once you are finished, submit the needed information for all five steps to this assignment!
